ADDING-MACHINE.

Specification of Letters Patent.

Patented. July 28, 1908.

Application filed November 30, 1906. Serial No. 345,805.

To all whom it may concern:

Be it known that I, JEssEG. VINCENT, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Adding-Machines, of which the following isa specification.

One object of the present invention isto provide a double capacity in a machine for performing the usualfunctions of an adding machine,- viz., accumulating, listing and striking totals of different amounts. In this same connection the invention provides for greatly increased facilities in the matter of tabulation as it is proposed to make. a single paper carria e and platen serve for both divisions of't e adding machine.

Eachsection or division of the double machine is inde endent of the other as to equipment for t e customary manipulation of amount keys and total and other special keys but only one section or division is equipped with means for directly applying driving power, provision being made for distribution of power between the two sections or divisions. When a motor is employed to take the place of hand-power in driving the machine, the one section or division will be equippedwith a starting device to be touched by the operator, and th usual safety device will be employed to prevent operation of this starting device While the total key of this section or division of the machine is partially depressed. Owing to the remotenessof the total key of the othersection or division of v the machine, and the many intervening parts between it and the starting device it is found impractical to use such a safety device in connection with this other total key. Therefore recourse is had 'to other means for protecting the ma chinefrom damage due to touching the starting device while .this particular.

. total key is but phartially depressed.

. According to e present invention a yielding character of connection is employed'to transmit power to those working 'parts of this other section or division of the machine which might otherwise be disastrously affected by an application of ,power to drive them whenthe totalkey was but partially depressed. v

A; similarcharacter of yielding connection is employed to fulfil a furtherobject of the invention which is to provide, in an adding machine equipped for operation either by I hand or by power, for completion of a cycle of operation of the machine when powerdriven notwithstanding interference with the proper action of the handle-shaft or attachments'; Thus while this operating. con nection is a rigid and positive one when conveying motion from the handle-shaft to the power-driven shaft when the operator is applying force by hand to operate the machine, yet said connection will yield when the initial movement of parts is being produced by a motor coupled to the power-driven shaft.

A still further, obj ect of the invention is to provide for completin by hand an operation of the machine-whichias been partially performed by the motor and accidentally interrupted. Thus provision is made for removing at will the obstruction otherwise present: ed by the motor-controlling detent devices to the application of the detachable handle to its shaft.

With these and incidental objects in view the invention consists in certain novel features of construction and combinations of parts the essential elements whereof are recited in the appended claims and a preferred form of embodiment of which is illustrated in the accompanying drawings and described in detail hereinafter.

Of said'drawings Figure 1 represents in right-side elevation an adding machine of the familiar Burroughs. type with the improvements of the resent invention embodied therein, the inc osing casing of the machine being shown in section as well as certain cross-rods or shafts and studs arid the'paper carriage attachment at the rear and a'portion of the motor casing being broken away to disclose interior parts, some in section and others" in side elevation; Fig. 2 represents a sectional right-side'elevation of part of the driving connections froni the motor; Fig. 3 represents in longitudinal section a telescopic link which constitutes the operating connection between thehandle-shaft and the powerdriven shaft; Fig. 4 represents a top plan view of the complete machine with portions of the casing broken away to disclosecertain parts on a lower plane and with the operating handleapplied; and Fig. 5 is a top plan view of the base casting on which the sup orting frame-Work is erected, thisview also s owing the power-driven shaft and immediate con-- nections.

.While the invention is here disclosed as .also the presence on the market of the Burroughs machine in'large numbers it willnot be at all necessary to a complete understanding of the resent invention by those skilled in the art t at this specification shall go further than to briefly specify a limited number of Burroughs parts'withwhich the cooperating elements of the present invention are immediately associated.

Within a sin le inclosing casing of proper dimensions an of panel formation are inclosed two complete adding and listing structures each comprising an accumulator and type-carriers with key-controlled mechanism for difl'erentially setting up types and correspondingly actuating the accumulator, these,

structures being capable of adjustment in the usual manner for the taking of totals and sub-totals. The skeleton or frame-like portion of the inclosing casing is designated by the numeral 1067 in Fi .4-and is of suitable formation to accommo ate side by side two complete key-boards,, one for each of the above-mentioned adding and listing structures, also controlling keys such as the socalled elimination, sub-total, total, error, and repeat keys, one set for each ke -board. The arrangement of the key-boards is such as to bring the transverse rows-of keys into alinement which is an advantage in tabulating work.

n rear of each key-board the cross-bar of the casin carries column-release keys 1097 of wellown construction and arrangement. The two groups of type-carriers 611 with their type-plates 618'ap'pear in plan viewin Fig. 4 Where the panel-plates 1016 of the casing are broken out and it is to be noted that there is a single platen roller 1799 common to the two groups of type-carriers and plates, this platen roller being sufficiently long to cooperate with either or both groups of type and allow for a sufficient range of lateral shift. Said roller platen is journaled in a paper carriage 1700 arrangedto slide transversely of the machine upon'suitable tracks supported by a bracket 1701 secured to the back of the casing (Fig. 1).

The above-described casing and the adding and listing structures are erected upon a single supporting base in the form of a'castin 1065 (Fig. 5) and said casting is provide with bearings 166 for a shaft 100 extending across the rear part of the machine for opera-.

tive connection with both of the adding and listing structures. Crank arms 110, 110 secured to this shaft are connected by springs 180 with the bottom of the casting chafacter such full-stroke and b other springs 181 with crank-arms of rock-s afts 800, respectively, of the adding and listing structures (that of the right-hand structure onl being shown, Fig. 1) and as in the case 0 the usual Burrou hs machine the springs 180 normally rock t e shaft 100 forward and the s rings 181 transmit movement from said shaft to the main working parts of the adding and listing mechanisms when said shaft' 100 is moved in-opposition to said springs 180, pitmen 119 producing the reverse or forward movements of the shafts 800. In the present instance as distinguished from the usual Burroughs construction a single drive shaft 100 is connected with the base casting through two different sets of springs 180 and with the two adding andlisting mechanisms through two different sets of springs 181 and pitmen 119. shaft may be rocked against the stress of the springs 180 either by hand or power. In the latter case the motor is arranged to operate directly upon, the shaft whereas when the shaft is to be rocked by hand the handle is applied to a separate shaft which is appropriately connected with the shaft 100. In the resent instance this separate shaft is part of t e right-hand section or division of the double machine. It is designated by the numeral 300 and has the usual location inthe frame and the usual formation to receive the detachable handle 368 (Fig. 4). Said shaft carries the usual sector 311 notched to cooperate with the familiar full-stroke device. It is well known that in machines of this devices are sometimes the cause of trouble on account of erroneous action in looking the handle. In order to prevent such action from interrupting a cylcle of operations set on foot by the motor t e present invention provides for a yielding of the drivin connections between the sector 311 and t e crank-arms 1 10 of the right-hand section or division of themachine.

Instead of employing the customary single-piece link, a telescopic form of connection is adopted, the same comprising a shouldered rod 353 pivotally connected with the sector 311, a tubular rod 351 similarly connected with the crank arms 110 and embracing the reduced portion of the rod 353, and a coiled s ring 383 embracing both rods and engage at opposite ends with spiral grooves therein, see Fig. 3. It will be seen that through this form of connection rigidity is insured when the machine is being operated by hand as in such case there is a direct thrust of the shoulder of the rod 353 against However, when 11;.

the end of the rod 351. power is applied directly to the shaft 10!) motion is transmitted to the sector 31] through the medium of the spiral spring 31;; andconsequently should he hill-stroke drvices go wrong and locksrld sector the inotm' can continue to. rock the shaft 100' by reason of the yielding of the spring 383; In the case of an electric motor this will have the advana stub shaft 3.00 similarly located -to the' tage of preventing burning out. This yield ing form of connection has an additional ad'- vantage in allowing for a slight'over-running when the motor rocks the shaft '100 therebydoing away with adjustmentswhich have heretofore been found necessary in order to insure correct timing. I

An exactly similar form of drivingconnection is used between the sector 311 of the left-hand section or division of the machine and the crank arms 110 of that section or division, said connection comprising telescopic rods 353 and 351 and acoiled sprin 383? (see Fig. This sector 311 is carried by shaft 300 but not formed for attachment of a handle, this shaft 300 being at an inaccessible position in the middle of the interior of the double machine; The sector 311 requires no full-stroke device as' it has no such association with the source of driving power arm ofthe total-key bell-crank 'lever 227.

as to serve a useful function in compelling full strokes in operatin themachine. Said sector does, however, su serve the customary functions of effecting automatic release of depressed amount keys in the lefthand section or division of the machine and of holding the total key of said section or division out or in as the case may be during an operation of the machine. For the latter purpose the sector carries a segmental flange 315 for co-action with a roll on an arm1414 which is coupled to the total key. Similar devices are employed in the right-hand section or di-- vlslon of the machine and reference may be had to the illustration thereof in Fig. 1 for a full understandin' of' the corresponding devices of the leftand section or division.- The segmental flange of the sector 311 is designated'3l5 and the co-acting roll-carrying arm 1414. The latter is secured to arockshaft 1400 which carries a crank-arm' l4l0 connected by ali'nk 1416 with the depending The roll or arm 1414 stands normally to the .1 rear of the flange 315 but clear of the forward end thereof so that depression of the total key is not obstructed. Complete depression of said key results in swinging the arm 1414 so far forward as to carry its roll. beyond the flange (see dotted lines Fig. 1). In the one case the total keyis locked out during an operation of the machine, or during the first half of an operation, by the engagement between the inner edge of the flange and t'e roll; in theother case the key is locked in y the engagement of the outer edge of the flange with said roll. Now if thetotal key should be but partially depressed and the roll 'on arm 1414 acrosszthe end of the flange when power is applied to drive the machine, serious damage would likelybe caused. In the the clutch to close.

right-hand section or division of the machine this can be and is guarded against by providing an interlock between the, total key and the starting device for the motor. However, the remoteness of the total key 293.(Fig. 4)

1 of the left-hand section or division from said .type and the armature shaft drives a worm 3697 (Figs. 1 and 2) and therethrough aworm 'wheel 3667 carrying one member of a. clutch in the form of an annular flange 3690. This flange encircles a peri herally recessed disk 3691 secured to a sha t 3600 carrying a cam 3668 which operates upon'a roller at the lower end of a link 3691% jointed to a crank arm 190 secured to the shaft 100, at about the middle of that portion of the latter which pertains to the right-hand section or division of the machine (Fig. 5).. Springpressed struts 3631 in the recesses of the disk 3691 are arranged toeflect a driving union between said disk. and the wheel 3667 but said struts are normally restrained by reason of the engagement therewith of pins or studs 3656 of a disk or plate 3610 '(Fig. 2)

rotatably mounted upon the shaft 3600.

This plate or disk is in turn restrained by the abutment of a stop strip 3617 thereon against detent plugs 3650 and 3651, These plugs are geared together by intermeshing segments 3616 and 3616 and the latter is formed integrally with an arm 3615 by which these detent plugs are rocked to release the late or disk 3610 and consequently permit p i The outerend of said arm is formed with an eye through which a I slides a round rod 3626 forming part 'of a vertical bar 3627 which extends upwardly adjacent the shaft 300 to a point below the key-board of the machine at the right. A nut 36% screwed on the lower end of said rod 3626 engages the underside of the arm 3615 so that elevation of the-bar 3627 will result. in rocking the detent plugs and closing the clutch in the manner described. A presser bar 3698 extendsalong the righthand side of the key-board and constitutes a starting device when the machine is motordriven. This bar is provided with legs 3622 and 3624 which engage levers 3612 and 3613, respectively, jointed together between pivots and normally upheld as to their outer ends by a connecting spring 3688. The lever 361 2 extends beyond its point of engagement with 3627 adapted, when the bar 3627 rises, to

cross the space through which the handle must be introduced. Now it might ha en that the operation of'the machine woul d be interrupted on account of some accident afiecting the motor so that the machine would be stopped'with this lug across the space through which the handle must pass in A being applied to the machine. In such case the operator might find himself in the redicament of inability to operate the mac e either by hand or power. To provide for this contingency the connection between the bar 3627 and t earm 3615 is of the sliding character above described and a spring 3687 envelops the rod 3626 between said arm and the shoulder formed on the bar 3627 where the said rod unites therewith, this spring roviding for the return of said arm 3615 a bug with the bar 3627 in an ordinary operation of I the machine by the motor and at the same time permitting the said bar to be drawn downwardly by hand in order to permit introduction of the handlefunder such conditions as above mentioned when an operation of the machine is to be completed by hand. Ordinarily the lowering of the bar 3627 takes lace automatically by reason of a rollerstud 3649 on the sector 311 operating against a lateral projection 3649 of the bar 3627, so as to return the detents to operative position before the stop-strip 3611 can return to its normal position.

The interlock hereinbefore mentioned between thestarting device and the total key of the right-hand section or division of the machine comprises a square lug 3655 on the lever 3612, and an arm 1415 secured to the shaft 1400 and having a segmental outer end portion which normally stands just in rear of and below said lug. When the total key is depressed said segmental end ortion at once passes forward under the lug t us preventing operation of the starting bar until, by comete depression of the total key, the rear end of said segmental beyond the lug.

[t now be seen that the construction herein disclosed is well ada ted to fulfil the objects rimarily stated. e double capacity of t e machine coupled with the independence of its divisions as to accumulation and listing of items and printing of totals,

portion passes forwardly supplies a want long felt in certain classes of cut of the work such for example as that pertaining to trial balances. In such case the debits can be put into one section or division and the credits in the other and the make-up of the machine allows for ample space between the debit and credit entries as recordeda thing not provided for in the so-called split ma chine with wide key-board.
